Abstract

Penggunaan kadaver di dalam studi medis sudah lazim digunakan terutama sebagai media pembelajaran dan pelatihan tindakan medis seperti bedah. Akan tetapi kadaver manusia membawa sejumlah masalah yang tidak dapat dihindari. Sehingga perlu dicari material substitusi yang dapat digunakan untuk mengganti kadaver. Penggunaan material substitusi ini perlu memperhatikan potensi Indonesia agar dapat membantu perkembangan bangsa. Indonesia sendiri merupakan negara penghasil karet alam terbesar kedua di dunia. Maka dipilihlah komposit karet alam sebagai pengganti kadaver manusia. Penelitian ini dilakukan untuk melihat karakteristik dari komposit karet alam yang disintesis tersebut. Selain itu komposisi material yang digunakan juga penting untuk diperhatikan. Material yang digunakan adalah foaming agent, gelling agent, curing agent, activator, stabilizer dan filler. Filler yang akan digunakan adalah nanosilika, kaolin dan kalsium karbonat. Material yang telah dibakar kemudian dikarakterisasi mekanik dengan Universal Testing Machine untuk menentukan modulus Young dan FTIR untuk melihat struktur gugus fungsi penyusun nanokomposit dari polimer karet alam ini. Pengujian sampel kontrol juga dilakukan pada sampel yang dibuat dari karet sintetis (silikon) dan daging sapi. Penelitian ini menghasilkan beberapa material yang memiliki kemiripan karakteristik mekanik dengan anggota tubuh bagian dalam.  Karet komposit lateks 50% dan Silikon 50% pengujian 1 (0,070 MPa) menyerupai kerongkongan (0,77 MPa) serta pengujian 2 (0,041 MPa) memiliki karakteristik mekanik yang menyerupai usus manusia (0,0356 MPa). Karet komposit lateks 75% dan Silikon 25% pengujian 1 (0,196 MPa) dan pengujian 2 (0.136 MPa), memiliki karakteristik menyerupai tulang rawan pada lutut pria remaja (0,13 MPa).
